I expanded a bit (not very impressive, I admit) on the user submitted class for extending simple
xml.
Below are some nice quick and dirty additional class functions I have needed to manage the back end
for plugging in flash parameters to dynamic actionscripted .swf files needing this xml data
generated dynamically and with working variable xml content data that the client maintains (yikes!).
Probably need some bad character checking in here somewhere?
<?php
$xml_data = '<?xml version="1.0" encoding="ISO8859-1" ?>
<root>
<image name="Banner 1" file="pic1.jpg" />
<image name="Banner 2" file="pic2.jpg" />
<image name="Banner 3" file="pic3.jpg" />
<image name="Banner 4" file="pic4.jpg" />
</root>';
class SimpleXMLElementExtended extends SimpleXMLElement{
public function getAttribute($name){
foreach($this->attributes() as $key=>$val){
if($key == $name){
return (string)$val;
}// end if
}// end foreach
}// end function getAttribute
public function getAttributeNames(){
$cnt = 0;
$arrTemp = array();
foreach($this->attributes() as $a => $b) {
$arrTemp[$cnt] = (string)$a;
$cnt++;
}// end foreach
return (array)$arrTemp;
}// end function getAttributeNames
public function getChildrenCount(){
$cnt = 0;
foreach($this->children() as $node){
$cnt++;
}// end foreach
return (int)$cnt;
}// end function getChildrenCount
public function getAttributeCount(){
$cnt = 0;
foreach($this->attributes() as $key=>$val){
$cnt++;
}// end foreach
return (int)$cnt;
}// end function getAttributeCount
public function getAttributesArray($names){
$len = count($names);
$arrTemp = array();
for($i = 0; $i < $len; $i++){
$arrTemp[$names[$i]] = $this->getAttribute((string)$names[$i]);
}// end for
return (array)$arrTemp;
}// end function getAttributesArray
}
$xml2 = new SimpleXMLElementExtended($xml_data);
print('<pre>');
print('NUMBER OF CHILDREN: '.$xml2->getChildrenCount());
print('</pre>');
print('<pre>');
print('ATTRIBUTE COUNT PER CHILD: '.$xml2->image[0]->getAttributeCount());
print('</pre>');
print('<pre>');
print('CHILD 0 ATTRIBUTE "name":
'.$xml2->image[0]->getAttribute('name'));
print('</pre>');
print('<pre>');
print('CHILD 0 ATTRIBUTE "file":
'.$xml2->image[0]->getAttribute('file'));
print('</pre>');
$arrTemp = array('name', 'file');
$arrResult = array();
$arrResult = $xml2->image[0]->getAttributesArray($arrTemp);
print('<pre>');
print('CHILD 0 ATTRIBUTE ARRAY: "name,file":<br>');
print(var_dump($arrResult));
print('</pre>');
$arrResult = array();
$arrResult = $xml2->image[0]->getAttributeNames();
print('<pre>');
print('CHILD 0 ATTRIBUTE NAMES ARRAY:<br>');
print(var_dump($arrResult));
print('</pre>');
print('<hr>');
$arrCompiled = array();
$arrCompiled = $xml2->image[0]->getAttributesArray($arrResult);
print('<pre>');
print('CHILD 0 DYNAMIC COMPILED ATTRIBUTE ARRAY: "key,value"<br>');
print(var_dump($arrCompiled));
print('</pre>');
?>
Outputs something along these lines below:
NUMBER OF CHILDREN: 4
ATTRIBUTE COUNT PER CHILD: 2
CHILD 0 ATTRIBUTE "name": Banner 1
CHILD 0 ATTRIBUTE "file": pic1.jpg
CHILD 0 ATTRIBUTE ARRAY: "name,file":
array(2) {
["name"]=>
string(8) "Banner 1"
["file"]=>
string(8) "pic1.jpg"
}
CHILD 0 ATTRIBUTE NAMES ARRAY:
array(2) {
[0]=>
string(4) "name"
[1]=>
string(4) "file"
}
CHILD 0 DYNAMIC COMPILED ATTRIBUTE ARRAY: "key,value"
array(2) {
["name"]=>
string(8) "Banner 1"
["file"]=>
string(8) "pic1.jpg"
}
I'm sure there is more to add/revise/simplify, but it's a fast start to working with
fairly simple xml schema/structures.
Would be interested is anyone knows of how we could revise this class to say perhaps evaluate the
nodes AND attributes for the same xml element... like image id attribute with say 4 image file name
elements?
Peace.
